v This invention relates-to mixers such as egg beaters or the like devices. y

I The objects of theinvention include the V provision of an'improved, durable and efficient device of this class which is easy and convenient to operate and isinexpensive and relatively simple to manufacture; and the invention accordingto one of its embodiments includes a quick de tachable receptacle cover. Further and mor'especific objects, features and advantageswill more clearly appear from the detailed description" given below taken in connection; with the; accompanying V drawings which form a part of \this'specification, the invention pconsistsing in "the novel features, arrangements, and combinations of parts embodied by way of example in the ap- 1 paratusherein described as illustrating pre- 1 ferred forms of the invention; I I s 2 In'the' drawings, Fig. 1 is a side'elevational view partly in section, showingia device embodying the invention; 1 Fig. 2 is a sectional :elevational view of parts of the deviceshown in Fig. '1; the sec- I 25ti0n being taken approximately alongthe section line 22 of Fig. 1; c Fig. 3 isa face view of a part of the oper- ,ating gear and handle for the device of Fig. 1;and l Fig.4 is an enlarged detail sectionalview j taken substantially along the section. line 4-4 of Fig. 1. v

Referring to the drawings finfurther detail,the device as shown may comprise a rigid 35 frame member upon which the various v 7 parts aremounted and secured. ,This frame I member may comprise an integral metallic casting preferably. formedof a light weight metal, such as aluminum or an inexpensive 7 alloy thereof. The upper part of the casting may be formed with 'an aperture 11 ,for receiving a'handle grip 12 made ofwood or other suitable material a'ndha'ving: a shank vfitting the aperture 11 and secured therein as iii-1 by, a transversely extending pin 13. The l lower portions of the frame member,although integrally formed; are preferably substantially bifurcatednand Lromp'rise the two i 'branches 14 and ;15 terminating in portions 2. 9} havinglongitudinalapertures as at16. The

"ATNTZ o cE intermediate portions of these two branches; 3

tional form of rotatable dash members and p 21 'mounted upon vertically extending rods 22and 23, the upper ends of these rods being received with thelongitudinal apertures 16 of the frame member. The lower end ofthe are preferably strengthened by web members i rod 22 may be bent in the form of a loop in the conventional manner as shown and with its other end extending upwardly ,to coin-:1

prise the rod 23. l v v The upper ends of the beater members 20 and 21 maybe bent at right angles andperforated to provide apertured lugs as at 24 and 25 secured together asby an eyelet member26.

The eyelet members are rotatablygreceivedQ 1; upon thesupporting rods 22 or 23, and also embrace pinion members as at 27 andfi28 1 formed of sheet metal and held flatwise by the plane; but in order that the sheetmetal teeth thereof may have a sufficient effective width for proper interengagement, they maybe bent at an angle with said plane whereby the preferably mounted so as to rotate in'the same general I teeth of the respective pinions cross each I other in engagement in the manner shown. When the rods 22 and 23 are assembled'in respect to the various rotatable parts-thereon,

shown in Fig. 4, to wit, the branches of the v frame member may each be provided with depressions as at 29 extending into the casting 2' transversely ofsaid apertures to points close to the aperture walls but without intersecting the same; 1 The metal' within the base oflsaid prick punchdriven in a direction towardthe with the rods 22 and23;

is apertures so that thefaperture walls are brought into a firm gripping relationship depressions may be'upset as by the use of=a '9 pinions as shown.

Fig. 3, may comprise adisc of sheet metal with slots 31 at its periphery, the side edge of the slots preferably extending radially of the disc, and the ends of the slots being closed by an integral peripheral portion 32. The

slots maybe spaced apart at a distance 2113- proximating their width. It has been found that an operating gear with tooth portions formed in this manner runs quitesmoothly, and is a very durable construction,in cooperation with sheet metal pinionmembers as above described; Furthermore, ordinary wearand bending of the pinion members within reasonable limits does not materially interfere with the free running cooperation of-the gear and pinions. The gear may be driven by a handle member as at and may be mounted upon a shaft 84 extending transversely of the frame member '10. The shaft 34 is preferably mounted within a pair of spaced bearing portions as at and 36 integrally formed with the bifurcated frame member respectively at points just above the apertured portions 1% and 15.

In order that the beater'gear and pinions may be maintained in smooth running order, it is apparentthat the gear and pinion teeth 7 must be kept in proper relationship, which necessitates rigid and durable bearing means for the rotating parts. However, from. a practical standpoint, it is also of'course of importance to substantially minimize the weight and size ofthe frame parts to avoid cumbersome constructions of awkward appearance. These various v limitations have been efliciently met by the construction here described. The gear shaft- EA is provided with a pair of durable spaced hearings to insure its proper alignment and yet since these bearing portions are located at points just above the aperturedportions 14 and lfiwhich receive the rods 22 and 23, and in the same general plane therewith, substantially no extra metal is required therefor. Eacli'branch 'of the bifurcated member therefore comprises one of thebearings together with a support for one of the beater rods, and-the two branches arestrengthened by the inter mediate web members without adding appreciably to the weight of the device or detracting from its smooth appearance. A. simple light Weight unbendable frame is thus provided which insures smooth operation ofthe gears. 7

Also, the cast frame member, when formed asshownin the drawings, notwithstanding the double bearing, is substantially free of cracks and crevices as often occur with stamped sheet metal frames and in'which dirt and food ingredientsmay become lodged or concealed.

As shown in the drawings, the beater may be provided with aquick-detachable receptacle cover comprising two substantially semicircular and complementary sheet metal cover portions 37 and 38 detachably joined -along the line of separation as by conventional engaging parts 39 arrangedso that the two cover portions may be flexed one upwardly and the other downwardy to disen- At the center of: tlieicover, portions may be cut away :asat 40 to provide space for the beater members. The cover portions 37 and 38 respectively may have supporting arms 41 and 4:2 secured thereto and extending upwardly and inwardly to the aperture 19 above referredto, the arms terminating at their upper ends respectivelyin hook portions 43 and 44 which engage the surface of the web member 18, then pass through the aperture 19 iii-crossed comple mentaryrelationship and thereafter engage the side surfaces of the web member 17, Thus the supporting arms ofthe' respective cover porticnsare provided-a quiclcdetach- I able hookengagement with the frainemenu her and while the cover engaging means 39 are in place the cover is securely hel in position. However, upon releasefof the engag ing means39 thejcover portions may be swung outwardly,upwardly and then the a further by reason of the manner of engagement of the supporting arms with the. walls of the slot 19.

Such construction not only permits the beater to be used with or witlioutthe cover but the coversecuring means 'when'tlius made to be quickly detachable, greatly facilitates proper cleaning of the entire device. J V l/Vhile the invention has been: described in detail with respect to a. particularpreferred example thereofwhich gives satisfactory results, 1t Wlll be understood by those skilled in the art; after understanding the invention, I

that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appendec claims'to cover all such changes and modifications;
